I very much liked an excerpt from this article: “They say that we know when we are full. But actually, we eat with our eyes, not with our stomach. In one study, we blindfolded adults and asked them to rate “strawberry” yogurt, which was actually chocolate yogurt. Without the visual cue people accepted what they were told. Time and time again, our research found that people will eat regardless of whether they’re hungry: the bottomless soup bowl study (people ate more when the bowl remained full), the chicken wing study (people eat more when the chicken bones are removed from sight) and the buffet studies (people ate more simply because the food was there). Another myth is that our stomach will take about 20 minutes to tell our brain that we’re full. But that only applies when we are consciously aware of what we are eating, not when we are mindlessly eating cheesy nachos while watching March Madness.”
